A storage part of a construction machine stores an operation target which is set as a target of an operation of the construction machine for moving a specific portion of the construction machine to a target position set as a destination to which the specific portion moves. A calculation part calculates an index value which serves as an index indicating a deviation between the operation target and an actual state of the construction machine. A control device is configured to cause a vibration applying device to perform a first vibration applying operation when the index value satisfies a predetermined first condition, and to cause the vibration applying device to perform a second vibration applying operation when the index value satisfies a predetermined second condition different from the first condition.

Construction machine

A dismantling system includes a dismantling machine including a tip attachment for dismantling an object to be dismantled, an imaging device that provides a field of view from a second viewpoint position for visually recognizing an object to be dismantled, which is different from a first viewpoint position of an operator, and a dismantling operation device that receives operation by an operator of the tip attachment for dismantling an object to be dismantled with respect to the field of view provided by the imaging device.

Dismantling system

The construction machine includes: an input interface which permits an input of a provisional target position of the attachment in a virtual space; a target position calculation part which calculates an actual target position that is a target position of the attachment in a real space from the provisional target position; an operational amount calculation part which calculates an operational amount required to make a current position of the attachment coincide with the actual target position of the attachment coincide with the actual target position with respect to at least one driven target selected from a lower traveling body, an upper slewing body, a working device, and the attachment; and a control part which controls an operation of one of the actuators for driving the driven target in accordance with the calculated target operational amount.

A hydraulic excavator includes a lower travelling body, an upper slewing body, a sensor which detects presence/absence of an obstacle in a monitoring region set around the hydraulic excavator in advance and a distance to the obstacle, a control unit which calculates first position information including positional coordinates of an obstacle relative to a reference position set in advance in the hydraulic excavator on the basis of a detection result obtained by the sensor, a time counting unit which acquires time information including time when an obstacle is detected, and a storage unit which stores log data correlating the first position information with the time information.
